STOP-COCK.

SPECIFICATION forming part of Letters JZatent No. 243,731, dated July 5, 1881.

Application filed February 23, 1881. (ModeL) To all whom it may concern:

Be it known that I,FREDERICK SOHRUMPF, of Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Stop-Cocks, of which the following is a specification.

' My invention relates to stop-cocks for shutting 011 the water in houses and for hydrants; and it consists in the peculiar novel devices to and combinations of devices embodied in my stop-cock, as fully hereinafter explained, and pointed out by the claims.

In the accompanying drawings, forming a part hereof, Figure l is a vertical section of the stop-cock, the connections with the same being shown in elevation, and the cock being turned. to shut 011' the supply of water and to allow the water in the house-pipes to run off into the sewer Fig. 2, a top view of the stop-cock, the dotted lines indicating the direct passage for the water-supply and Fig. 3, a bottom view of the cook or valve.

Like letters denote corresponding parts in all three figures.

A is the case of the stop-cook, which has a tapered bore, as shown, and a screw-cap, a.

To opposite sides of the case A are connected the water-pipes B O, the pipe B being connected with the water-main in the street, while the pipe 0 is connected with the system of pipes in the house.

From the bottom of the case A projects downwardly a short pipe, D, surrounded by a box, E. Out of the side of this box, above 3 5 the lower end of the pipe D, extends a pipe,

F, which is connected with the sewer G.

H is the cook or valve, which is tapered to fit the bore of the-case A. It has a waterpassage, 1), extending horizontally straight 40 through the same on a level with the pipes B G, and at right angles to the passage 1) the valve has a curved passage, 0, extending from the side of the valve on a level with the pipe 0 and through to the bottom of the valve, connecting with the waste-pipe D, and thus making a three-way cook or valve. The valve is provided with shoulders (I d on its bottom, which strike a stud, e, projecting upwardly from the bottom of the valve-ease. The shoul- 5o ders and stud limit the movement of the valve. When water is being supplied to the house the valve is turned so as to bring the passage b in line with the pipes B 0, one of the shoulders d d resting against the stud e. The water then flows from the pipe B through 5 5 the stop-cock to the pipe 0, and thence into the system of pipes in the house, all connection with the waste pipe D being cut off. Now, when it is desired to shut the water off from the house, the valve is turned until the other shoulder strikes the pin 6. This movement closes the pipe B and brings the passage 0 into connection with the house-pipe O, as shown in Fig. 1. The water in the system of house-pipes then runs back into the stop-cock and passes out through the pipe D, box E, and pipe F into the sewer Gr.

It will be seen that, the water having a free outlet into the sewer, and the pipes D and F being of the same size, or nearly the same size, as the pipes B G, the water will run quickly out of the house-pipes before it can possibly freeze. The water being carried ofi by the sewer, instead of being allowed to soak into the ground beneath the cellar-floor, no dampness can result, and other objections to the method heretofore employed will be overcome. The water-seal formed by the box E prevents the sewer-gas from entering the cook or water-pipes.

The valve-stem f projects up through the cap a, and is squared to receive the socket I. This socket is attached to the lower'end of the rod K, forming therewith the turn-key for operating the valve. Heretofore the weight of this turn-key has been wholly supported by the valve-stem, and that weight, together with the pressure brought to bear upon such turnkey, has often forced the valve into the bore of the case and caused it to stick so that it could not be turned. This objection I overcome by making the stem f and socket I of such relative length that the socket will rest on the cap a, as shown, such cap being provided with a central annular projection, g, for 5 that purpose.

These same devices can be applied to hydrants without material modification, as will be readily understood.

What I claim as my invention is-- 1. In a stop-cock, the combination, with casing A, having water-pipe branches B 0, bottom waste-pipe, D, and screw-cap a, of the tapered valve-plug H, having horizontal passage b, and the curved downward leading passage o, and arranged to either connect pipes B O, or with a quarter-turn to connect pipes O and D, all substantially as and for the purpose described and shown.

2. In a stop-cock for the purpose set forth, the combination, with the casing A, having screw-cap a,and the valve-plug H, having
